Abstract

An adhesive composition that contains a preservative is particularly useful as a medical adhesive and can include alkyl cyanoacrylate monomers. The preservative is preferably soluble in the monomer. The composition may optionally be sterilized by placing a mixture of a polymerizable adhesive monomer and a preservative in a container, sealing the container, and sterilizing the mixture and the container.
